Corrosion Resistance Guide
Estel Body Material of
Optic Level Sensor and Thermistor
Level Sensor
This chart is intended as a general
guide and has been complied from
many sources believed to be reliable,
however, no guarantee is implied.
Because of the extensive scope
of this field, the tabulation is not
complete or conclusive. Corrosion
rates vary widely with concentration,
temperature and the presence of
abrasives. Impurities or other trace
elements common in industrial
liquids may inhibit or accelerate the
reaction of the material.
Key to Ratings:
A: No effect
Usable
B: Minor effect
Usable, but life my be
shorter than usual
C: Fair to poor
Do not use
D: Not recommended Do not use
